Description

The AT27LV040A is a high performance, low power, low voltage, 4,194,304 bit one-

time programmable read only memory (OTP EPROM) organized as 512K by 8 bits.

It requires only one supply in the range of 3.0 to 3.6V in normal read mode operation,

making it ideal for fast, portable systems using battery power.

Atmel’s innovative design techniques provide fast speeds that rival 5V parts while

keeping the low power consumption of a 3V supply. At V = 3.0V, any byte can be

accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5

MHz and V = 3.3V, the AT27LV040A consumes less than one half the power of a

standard 5V EPROM. Standby mode supply current is typically less than 1 µA at

3.3V.
